Packet supervisory mode

摘要

A packet monitoring system includes nodes, a monitor node, and a network management system. The nodes are connected to the same network and assigned different addresses. The nodes switch packets in which destination addresses in the network are written, in accordance with the destination addresses. The monitor node is assigned a unique address different from the addresses of the nodes. The network management system issues a request for a packet to the nodes. The request from the network management system contains the unique address of the monitor node. Each of the nodes copies the packet before switching the packet, and transmits the copied packet to the monitor node in accordance with the unique address contained in the packet request from the network management system. The monitor node monitors the copied packet from each of the nodes. IMAGE
